| Summary: | This thesis explores the methods necessary to modify an available XPlane10 aircraft model <br />
<br />
<br />
in the hopes of achieving an accurate overall performance, cruise lift over drag characteristic, as <br />
<br />
<br />
well as the pitching moment characteristics of an aircraft model in the XPlane10 simulator. The <br />
<br />
<br />
main idea of the method underwent in this thesis is by deciding several fixed parameters that are <br />
<br />
<br />
known to be accurate and the modification of several unknown variables to adjust the outcome <br />
<br />
<br />
of the simulations. The aircraft model this thesis is exploring is the Airbus A320-216 single aisle <br />
<br />
<br />
twin engine transport aircraft. <br />
<br />
<br />
The fixed parameters of the aircraft model in this thesis are the geometry of the main <br />
<br />
<br />
aircraft components to ensure a proper reference geometry, as well as the weight and balance <br />
<br />
<br />
parameters, such as the MTOW, empty weight, fuel load, CG range, fuel tank locations and <br />
<br />
<br />
volumes. <br />
<br />
<br />
The modifiable variables are the 2-D airfoil drag characteristics as well as the engine SFC. <br />
<br />
<br />
These values are modified according to latest outcome of the simulation and how they compare <br />
<br />
<br />
to the reference values. <br />
<br />
<br />
The final analysis suggests that the resulting aircraft model can only be used accurately and <br />
<br />
<br />
dependably in a very narrow range of cruise flight conditions. They are between the elevation of <br />
<br />
<br />
FL290 to FL350, with a total CL value of around 0.3, and a cruise duration of over one hour long. <br />
<br />
<br />
To improve the range of dependable flight condition, there should be more reference data <br />
<br />
<br />
to increase the number of fixed parameters as well as deciding more modifiable parameters to <br />
<br />
<br />
improve the fine-tuning of the outcome of the simulations. <br />
